<!-- =========== START OF MODULE DESCRIPTION =========== -->
<h2 class="module">Module openid.association</h2>

<p>This module contains code for dealing with associations between 
consumers and servers. Associations contain a shared secret that is used 
to sign <code>openid.mode=id_res</code> messages.</p>
Users of the library should not usually need to interact directly with 
associations. The <a href="openid.store-module.html" 
class="link"><code>store</code></a>, <a 
href="openid.server.server-module.html" 
class="link"><code>server</code></a> and <a 
href="openid.consumer.consumer-module.html" 
class="link"><code>consumer</code></a> objects will create and manage the 
associations. The consumer and server code will make use of a <code><a 
href="openid.association.SessionNegotiator-class.html" 
class="link"><code>SessionNegotiator</code></a></code> when managing 
associations, which enables users to express a preference for what kind 
of associations should be allowed, and what kind of exchange should be 
done to establish the association.
